The 1990 Florida gubernatorial election took place on November 6, 1990. Incumbent Republican Governor Bob Martinez ran for a second term in office, but was defeated by Democratic challenger Lawton Chiles, a former U.S. Senator.
The 60-year-old Chiles, who retired after three terms from the Senate in 1989 after serious health problems, was challenged by the younger 47-year-old Nelson, who questioned his health in the campaign and presented himself as alternative.
This, however, backfired on Nelson and cost him the election; the elderly population in Florida took great offense to Nelson's attacks and, in turn, voted for Chiles.
